UNITED STATES JOHN B. .ARPIN, OF WISCONSIN RAPIDS, WISCONSIN.

ILAN'I FOR SEPABATING COKE.

Application filed. July 28, 1922. Serial No. 578,068.

To all whom it may concern:

Be it known that 1, JOHN B. ARPIN, a citizen of the United States, and a resident of Wisconsin Rapids, in the county of Wood and State of Wisconsin, have invented certain new and useful Improvements in a Plant for Separating Coke; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to apparatus for recovering coke from ashes.

It is an object of this invention to provide a plant for this work which shall not require the presence of astream of flowing water, but may be used on the shore of standing water, or at sea.

It is a further object of this invention to provide a means for rapidly and inexpensively separating coke from ashes whereby either the coke, the clinker or the ashes may be handled directly from railway cars.

It is a further object of this invention to provide apparatus to care for changes in conditions or in the character of the ashes even when such adjustment requires the movement of a large weight of ashes.

Other and further important objects of this invention will be apparent from the disclosures in the accompanying drawings and specification.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

"On the drawings:

Figure 1 is a top plan View of the plant.

Figure 2 is a side view.

Figure 3 is an end view.

Figure 4 is a section upon the line 4-4 of Figure 1.

Figure 5 is a section upon the line 55 of Figure 1.

Figure 6 is a top plan view of the parts shown at theleft of Figure 4.

Figure 9 is an enlarged view partly in section of a detail showing the scraper associated with the belt at the left hand part of Figure 1.

a means for nice adjustment of the As shown on the drawings:

A railway track 10 is provided by which ashes may be brought to or coke or clinkers carried away from the plant. Besides-the track 10 are bins 11 for the reception of ashes. The ashes from these bins descend upon two conveyor belts 12, shown in Figure 8. These belts are driven in any convenient manner so that they run from the two ends of the row ofbins toward the center. In the form illustrated, they are driven by a pair of gear wheels 13,'which receive their power from a sprocket chain which leads to any suitable source of power. The conveyor belts deliver into a chute 15 which leads the ashes to a rotating sieve 16 driven by a sprocket chain 17 receiving its. power from the shaft of one of the rollers 13. The rotating sieve has an axis which is not horizontal but slopes slightlydownward and away from the belts. The lower end of the sieve is located above a receiving funnel 20 which delivers intothe pipe 21. This pipe leads from a'nelevated tank 23 which will be described below.

The delivery end of the pipe 21'is over a funnel-shaped car 24 which is supported upon a raft 25. The pipe 21,- therefore, must be long enough to reach from the structure near the tracks on the shore to a point beyond the shore where'the water is deep enough for the operation described below. Upon the raft 25 are two rails, one of which 26 may be any ordinary type of railroad rail. The other 27 is preferably in the form of a rack bar. The wheels of the V car 24 are made to correspond, those illustrated in Figure 4, therefore, being cog wheels for co-operation with the rack. One axle of the car is provided with a worm wheel 30 adapted to be driven by a screw 31 and by a hand wheel 32. By the rotation of the hand wheel 32, therefore, the position of the car upon the tracks 26 and 27 may be adjusted with great nicety.

The raft 25 is held in place by means of piles 40 or in any other desired manner. The raft is in the form of a frame surround ing a well. From one side of this well goes a mouth or funnel 41 leading to a pipe 42.

The side of the well has an opening for j the large end of the funnel 41. From the lower edge of this opening the wall of the well slopes downward and toward the center of the well forming a baffle plate 44 which leads material onto a conveyor 45 extending obliquely upward and through an opening in .the other side of the well.

This conveyor extends beyond the surface of the water to any convenient point (not illustrated).

The funnel 41 is rectangular in cross section to extend across the whole of one side delivery of the well. The opening in this. side of.

the well is suflicient to permit the funnel a considerable vertical movement. This movement is provided for by a hoist including a cable 46. The A frame for this hoist extends from one side of the raft as shown at 47. By lifting or lowering with this hoist the height of the entrance edge of the mouth 41 may be varied. In order that no material may escape above the mouth 41, a

- plate 48 is provided secured below the water plate is thus made to contact 23 From the pipe 51 the water is dis 1 the. pipe -2 1, as first described. The coke that the coke thereon charged against'a screen 53, as best shown in Figure 5. The water passes through this screen and descends to the bottom of the tank 23 from whence it. passes out through which traveled in pipes 42 and 51 with the water descends the screen 53 and is received upon a, conveyor belt 55. The belt is not,

horizontal buttravels up a gradual slope so may have ample opportunity to drain. 7

At intervals, along the belt scrapers 57 are located. As shown in Figure 9, these scrapers are mounted upon pivots 58 secured to the wall 59 which forms one side of a set of bins 6O situated below the tank 23 and over 9, coke may bin.

the track 10 and into which the conveyor belt 55 delivers. scrapers,

By lifting one of the as shown in dotted lines in Figure be permitted .to pass further along the belt and so delivered to a, bin further from the tank 53,.but by lowering the scrapers into operative position, the coke may be made to leave the belt at the first The bins terminate in a series of months 61, each closed by a suitable gate 62 so that they will deliver only when the gate is opened, which will be done when a railroad car is situated beneath the bin.

In the operation of the device, the ashes is loading mechanism from the railroad cars.

9 Itv descends these bins and arrives on the V conveyor belts 12 which deliver it to the chute 15, from whence it passes through the rotating sieve 16. The finer part of the ashes passes through the meshes of this placed in the bins 11 by any suitable unsieve; the coarser part travels the lengthof thesieve and is delivered into the funnel 20 and so introduced into the pipe. 21. The

stream of water flowing through this pipe carries the ashes through it to the car 24.

The funnel shape of this can causes the ashes above the lower edge of the mouth 41 should,

be great enough to permitthe current to produce an ample separation between the lighter coke and the heavier clinker. If possible, a place should be selected for the plant where the depthof the water is suf permit this height to be, iat-least ficient to six feet. g

The division between the a coke and the clinkers can be regulated by means of the hoist, the cable 46 raising orlowering the .It, may" als lower edge of the mouth- 41 be regulated by the wheel. 32, moving the car 24 slightly toward or away from the mouth 41. The coke ismoved into the mouth 41.

by the current through. thevwell. vOnce inside the mouth, the current is confined by r the walls ofthe passage and the coke is through the The water passes through thisscreen and down the pipe 21, thereby supplying ample current to move the coke from the funnel 20'to the car 24. The coke from pipe 51.

'rolls downthe-screen 53,.being largely septherefore moved with. certainty. It passes". pipe 52 and is sent'by the pump '50 through the pipe 51 onto the screen 53.

one of the scrapers 57' and falls into one of s the bins 60. When aicar on the track 10 is positioned under the mouth 61, the gate 62 will be opened and a supply of coke from the bin will descend into the car. The car will then transport the coke to the desired place. v

If desired the screen 53 may be made to slope the other way so that the flow of water from the pipe 51 shallassist the motionof the coke down the screen. 'Also the parts V of the apparatus shown as on shore may. be mounted on a scow or skill' or other vessel if it is desired to have the wholeapparatus atsea. j p I am aware that numerous detailsof construction may be varied through a Wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
